Paul and fellow Jetspeed users, I think that might be the case. In the past I tried to accomplish the same with an Applet, with more or less the same result (ExceptionInInitializerError ). When asking the author about this problem I got a very short, but explicit answer: "JCo cannot be used in Applets." I am still pursuing this problem, even mailed the author again. When I hear anything, I will inform you.

Try writing a JSP that uses jCO.jar. This will simplify the problem.
